Frequently asked questions
FAQYes, this toner is considered safe for use during pregnancy and breastfeeding. Niacinamide (Vitamin B3) is FDA-approved and has not been associated with any adverse effects during pregnancy.

However, always consult your healthcare provider before starting any new skincare products during pregnancy.
Yes, this product is fungal acne safe. The formula is free from ferments, fatty acids, esters, polysorbates, and oils that feed Malassezia yeast. Niacinamide is water-soluble and does not provide a food source for the yeast that causes fungal acne. The minimal ingredient list makes it an excellent choice for those prone to pityrosporum folliculitis.
With Retinol: Yes! Niacinamide can actually help reduce retinol-induced irritation while boosting skin barrier function. Layer niacinamide first, then retinol.
With Vitamin C: Use caution with pure L-Ascorbic Acid. While they won't harm skin, they may reduce each other's effectiveness. Use vitamin C in AM and niacinamide in PM, or wait 15-30 minutes between applications.
With AHA/BHA: Yes, niacinamide pairs well with acids and can help reduce potential irritation. Apply niacinamide after your acid treatment has absorbed.
This toner works best for oily, combination, and acne-prone skin types due to its sebum-regulating and pore-minimizing benefits. It's also excellent for those with hyperpigmentation or uneven skin tone. Sensitive skin types can use it but should start slowly and patch test first. Dry skin types may find it too lightweight on its own and should layer with additional hydrating products.
Results timeline varies by concern:Hydration and texture improvement: 1-2 weeks.Oil control: 3-4 weeks.Pore refinement: 6-8 weeks.Brightening and dark spots: 8-12 weeks of consistent use. For best results, use twice daily (AM and PM) and always follow with sunscreen during the day.

You can apply it with a cotton pad, your hands, or as a toner mask. It can also be mixed directly into your other products at 5-10% concentration for a DIY boost.
No, this toner has a comedogenic rating of 0/5 and will not clog pores. The lightweight, water-based formula contains no oils, silicones, or heavy emollients. In fact, niacinamide actively helps minimize the appearance of pores and regulate sebum production, making it beneficial for preventing clogged pores and breakouts.
The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight and keep the cap tightly closed after each use. The preservative system (1,2-Hexanediol and Ethylhexylglycerin) helps maintain stability and prevent contamination throughout the product's lifespan.
Verdict: ONE THING Niacinamide 10% Toner is an outstanding choice for anyone seeking a no-nonsense, high-concentration niacinamide product. Its ultra-minimalist 5-ingredient formula makes it exceptionally safe for sensitive, pregnant, and fungal acne-prone skin while delivering proven brightening and oil-control benefits. The generous 150ml size offers excellent value compared to competitors. While the watery texture may require layering for dry skin types and results take consistent use to appear, this K-beauty essential earns its cult favorite status as a versatile, effective, and affordable treatment toner.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
